This invention relates in general to an extension table and has more particular reference to a sectional sliding table top with foldable extension leaves concealed below the top. 5 In an extension table it is some times desirable to insert only a single extension leaf, but two or more extension leaves of this kind may also be inserted if desired. Where there are two extension leaves and the table top consists of two oppositely moving sections, it is necessary to provide means for centering each of the folding leaves between the extension topseetions. When the extension leaf is removed it is necessary to position it at one side of the other leaf in order that it may fold below the table top, and to insure that it will be free from contact with the other table leaf.

An important object of the invention is in the provision of means in connection with the table top sections for positioning` either or both of a pair of folding leaf sections so that they may be properly stored below the `table top when the leaves are rotated to their concealed position. A further object of the invention is in the provision of non-interfering selective means for engaging and withdrawing either one or both of a pair of folding table leaves from a central position to a lateral position in which they may be inverted below 30 the table top. Other objects will appear hereinafter, the drawings illustrating a preferred embodiment of the invention. In the drawings;

Figure 1 is a plan view with parts broken away for clearness of an opening extension table constructed in accordance with the principles of this invention;

Figure 2 is a sectional view taken on the line 2-2 of Figure 1; and

Figure 3 is a sectional view showing one of the extension leaves in its open or extended position.

This invention is shown as applied to a stationary table base 4 which has a pair of top sections 5 and 6 movable oppositely at the top of the table base by means of opposite metal racks 7 and S secured to the under side of each table section and engaging at the center with a, pinion 9 which causes the opposite relative movement of the top sections.

In order to hold the table top sections t0.- gether, a pivoted latch 10 isl mounted at the under side of one of the table sections and has a fixed catch 11 engaged thereby at the under side of the oppositev section. To release the catch l() an operating rod 12 having an engaging head 13 is carried by one of the top sections and is movable to release the latch 10 when it is desired to extend the table top.

As the table top sections 5 and 6 are connected for simultaneous opposite movement, a single extension leaf must be centered between them when it is desired to increase the size of the table top by one leaf only. In the present invention provision is made for a pair of folding leaves which are concealed below the table top in closed position and either one or both of these folding leaves may be inserted and centered between the table top sections, and either one or both of the extension leaves will be withdrawn to the proper position when the table top sections are moved apart in reducing the size of the table.

To accomplish this result, a pivoting rod 15 extends lengthwiseof the direction of movement of the table top sections 5 and 6 and is fixed at 'the ends of the supporting base l or frame of the table. Pivoted upon the rod 15 are a pair ofv folding, sectional table leaves, each comprising sections 16 and 17 connected by a hinge 18 invisiblev from one side of the leaf thus formed when the leaf is unfolded or extended. The uppermost section 16 in folded position is provided with brackets 19 and 2O each having a perforated upstanding leaf through whichthe rod 15 extends, one located close to the outer edge of the table leaf and the other bracket 2O spaced at a distance less than one half of the width of the table leaf from the opposite or inner'edge thereof. In its folded and concealed position below the table top, the folding leaves maybe supported in any suitable manner, as, for Vexample, by means of a rod 21 which extends parallel with the pivoting rod 15 and at one side thereof.

Hooks 22 and 23 are secured to the under sides of the table top sections 5 and 6, extending inwardly toward each other and in position to engage the upstanding leaf of the outermost bracket 19 of the folding leaf adjacent thereto but not engaging the upstanding leaf of the bracket 20 which is reduced in width adjacent the pivoting rod 15 so that the hook 22 or 28 will pass by the upstanding reduced leaf portion of bracket 20 in either direction but will engage the upstanding leaf of bracket 19 which is of full width. One of the hooks 22 or 28 is offset with respect to the other so that when the table top ysections are moved together these hooks will not engage but will pass freely by each other, allowing the top sections to move close together where they may engage and are held in tion by the latch 10;

With this construction it is obvious that either leaf may be rotated by the pivoting rod 15 when the table top sections are moved apart, and when the sections are moved together the unfolded leaf will be confined at the center of the table between the two top sections. In withdrawing the extension leaf thisaction is reversed. The table top sections are first moved apart; with this construction the proper hook 22 or 23 will engage its corresponding bracket 19 as the top sections are moved apart and will withdraw the centered folding leaf to its proper position without separatelyand manually engaging and operatingthe leaf. The extension leaf is then folded or collapsed and rotated below the level of the table top into its concealed position. Y

The inner brackets 20 are located, as explained, so that either leaf may partially overlap the other without causing an engagement of the brackets 20 and each bracket 20 is cut away so that the hooks 22 and 23 will pass by them without engagement.

If both extension leaves are unfolded and extended, it is apparent that they'will both be returned by their respective hooks 22 and 23 as the table top sections are movedapart. Y

It will be observed that provisionis made for spacing the folding leaves apart yand from the adjacent edges 0f their respective table top sections a distance sufficient to clear the dowel pins Y which are commonly employed with extension tables and leaves to hold the parts in proper alignmentvwhen they are moved together.

, While I have thus disclosed a preferred embodiment of my invention, it is obvious that various changes may be made without departing from the spirit and scope of my invention.
